Description
I was about to create a QtWidget-based project. When it came to the part when I had to choose which kit I would like to use, I choose "Manage..." and deleted an old kit (denoted by a yellow warning sign). When I clicked on "Apply", QtCreator crashed.
I tried later and removed that kit using Tools > Options > Build and run and with that method everything went successfully.
Console log:
QObject: shared QObject was deleted directly. The program is malformed and may crash. Program received signal SIGSEGV, Segmentation fault.
